[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-3This utility model provides a technical solution: a rewinding machine for paper roll production, including a base plate 1, a side plate 2 fixedly mounted on the base plate 1, a freely rotatable roll 3 and take-up roll 4 mounted on one side of the side plate 2, a sliding opening 5 between the take-up roll 4 and the roll 3 in the side plate 2, a slider 6 slidably mounted in the sliding opening 5, a pressure roller 7 rotatably mounted on one side of the slider 6, and a motor 8 fixedly mounted on the other side of the slider 6 for driving the pressure roller 7 to rotate. The movement of the slider 6 allows the pressure roller 7 to rotate. Pressed against the take-up roller 4, the pressure roller 7 presses against the take-up roller 4 or the surface of the paper wound on the take-up roller 4 to provide power to the take-up roller 4, so as to wind the paper on the roll roller 3 onto the take-up roller 4. The pressure roller 7 acts as the active roller to control the winding speed, ensuring that the winding speed does not change as the diameter of the take-up roller 4 increases, making the winding speed more stable. The side plate 2 is equipped with a drive unit for driving the slider 6 to move toward the take-up roller 4, so that the pressure roller 7 can press against the take-up roller 4.

[0020] Specifically, the drive unit includes a counterweight 9 and a guide wheel 11. The guide wheel 11 is rotatably mounted on the other side surface of the side plate 2. An extension rod 12 is fixedly mounted on the slider 6. A pull rope 10 is fixedly connected to the counterweight 9. The pull rope 10 is wound around the guide wheel 11 and then fixedly connected to the extension rod 12, so that the slider 6 is pulled towards the take-up roller 4 by the weight of the counterweight 9, ensuring that the pressure generated by the pressure roller 7 on the take-up roller 4 remains unchanged when the diameter of the take-up roller 4 changes.

[0021] Furthermore, the counterweight 9 is composed of multiple detachable counterweight pieces. By increasing or decreasing the number of counterweight pieces, the total weight of the counterweight 9 can be changed, thereby controlling the pressure of the pressure roller 7 on the winding roller 4.

[0022] Furthermore, a pair of guide rollers 13 are rotatably mounted on the side plate 2, and a pair of guide rollers 24 are rotatably mounted on one side of the slider 6 below the pressure roller 7, so that the paper can be wound on the take-up roller 4 for at least three-quarters of a turn before contacting the pressure roller 7, ensuring friction between each layer of paper and preventing slippage between the layers of paper from affecting the transmission effect between the pressure roller 7 and the take-up roller 4.

[0023] Furthermore, the surface of the pressure roller 7 is provided with an anti-slip layer to increase the friction between the pressure roller 7 and the paper.

[0024] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0025] The working principle and usage process of this utility model are as follows: In use, the roll material is installed on the roll roller 3, and one end of the paper is pulled out and passed through the guide roller 13 and the guide roller 2 14 before being connected to the take-up roller 4. The pressure roller 7 is pressed tightly onto the take-up roller 4 by the pulling force of the counterweight 9. Starting the motor 8 can make the pressure roller 7 rotate. The pressure roller 7 can drive the take-up roller 4 to rotate by contacting the take-up roller 4 or the paper wound on the take-up roller 4, thereby realizing the winding of the paper. The pressure roller 7 acts as the active roller to control the winding speed, ensuring that the winding speed does not change as the diameter of the take-up roller 4 increases, making the winding speed more stable. When the diameter of the take-up roller 4 increases, the slider 6 moves outward, which at the same time pulls the counterweight 9 upward, but the pulling force generated by the counterweight 9 on the slider 6 remains unchanged. Therefore, the pressure of the pressure roller 7 on the take-up roller 4 remains constant, ensuring that the tightness of the paper wound on the take-up roller 4 is consistent and improving the winding quality.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
